Respiratory Masks TRIZ Cases

Grip-enhancing end moldings and a conical sealing area help respirator tubes align faster, detach more easily, and stay cleaner.

A pressure-responsive membrane balances multiple vent orifices to keep respiratory therapy airflow stable while reducing noise and fit-related discomfort.

A guarded valve arrangement keeps a full face mask sealed during therapy while preserving ambient air passage when pressure support stops.

A resilient snap-fit connector locks the patient interface to oxygen tubing to prevent misconnection and accidental disconnection during use.

A nested vent adaptor with HME maintains stable vent flow, improves connector alignment, and minimizes dead space in respiratory therapy.

A fusible retainer and spring-biased valve cut oxygen flow during fire, improving patient safety without adding line weight.

A variable-thickness vent membrane deforms with pressure to keep CPAP bias flow steady, cutting noise, drafts, and flow source demand.

A deformable vent membrane narrows the flow opening as pressure rises, stabilizing CPAP bias flow while cutting noise, drafts, and power use.

Pins and a chamfered weld surface focus HF energy through overlapping headgear straps while reducing burns, bulges, and visible marks.

Peak voltage capture at touch electrodes defers DSP until after sampling, reducing compute load while preserving fast capacitive detection.

By capturing electrode peak voltage before digital processing, this case speeds capacitive touch detection while reducing computing load.

Peak-voltage sampling and deferred DSP cut touch-sensing compute load while preserving fast, accurate capacitive input detection.

Peak voltage sampling defers full DSP until electrode capacitance peaks are captured, cutting compute load, power draw, and touch response time.

Elongated vent channels replace small exhalation holes to discharge breathing gas quietly, at lower velocity, and with better diffusion.
